We use either electric or propane style Smokers in this part of the world.
Wood Pellet Smokers come in third place.
The real difference is whether you want to cold smoke or cook and smoke....where keeping the Temperature down to 250 degrees F or less for Cold Smoke.
Cold works better for fish and other delicate food items... and hot smoke works better for red meats...beef, pork, goat.
Hit that shopping place named after a South American River and do some searching.
Charcoal fuel is not a choice by the way.
Here is a good place to start as well.....the important thing is to read the Reviews/Ratings and consider what kind of smoking you are wanting to do.

My next investment for my Cottage at the Coast is this Gas Grill.....built locally and comes with a Life Time Warranty on the Gas Burner.
The Builder will ride his Harley to your front door and replace the burner if it every goes bad.
Perhaps not if you live on the other side of a saltwater divide.
We take our cooking serious in these parts!
